New particle formation (NPF) represents the first step in the complex processes leading to
formation of cloud condensation nuclei. Newly formed nanoparticles affect human health, air …

Aerosol particles in the atmosphere profoundly influence public health and climate. Ultrafine
particles enter the body through the lungs and can translocate to essentially all organs, and …

Fundamental questions remain about the origin of newly formed atmospheric aerosol
particles because data from laboratory measurements have been insufficient to build global …

Atmospheric new particle formation (NPF) is an important phenomenon in terms of global
particle number concentrations. Here we investigated the frequency of NPF, formation rates …

Homogeneous nucleation from the vapor phase has been a well-defined area of research
for∼ 120 yr. In this paper, we present an overview of the key experimental and theoretical …

Formation of new aerosol particles from trace gases is a major source of cloud condensation
nuclei (CCN) in the global atmosphere, with potentially large effects on cloud optical …

Molecular clustering is the initial step of atmospheric new particle formation (NPF) that
generates numerous secondary particles. Using two online mass spectrometers with and …

There is increasing evidence indicating the critical role of ammonia (NH3) in the formation of
secondary aerosols. Therefore, high quality NH3 emission inventory is important for …

We report comprehensive, demonstrably contaminant‐free measurements of binary particle
formation rates by sulfuric acid and water for neutral and ion‐induced pathways conducted …

In this perspective, we review experiments with molecules picked up on large clusters in
molecular beams with the focus on the processes in atmospheric and interstellar chemistry …
